Patent number: 11218004Abstract: An arrangement having a multifunctional connection for energy storage cells or energy consumers provides at least one device for charge equalization and/or a measuring device for measuring an electrical voltage of energy storage cells or energy consumers; an electrical bridging element between two electrically insulated conductors; and a trigger circuit for activating the bridging element. One of the two electrical conductors is connected or is connectable to a first pole in an electrically conductive manner, and the other electrical conductor is connected or connectable in an electrically conductive manner to a second pole of the energy storage cell or of the energy consumer. The device for charge equalization and/or the measuring device is connected to the electrical connection of the bridging element. The electrical connection can thus be used simultaneously for triggering the bridging element and for the charge measurement and/or the charge equalization.Type: GrantFiled: May 16, 2017Date of Patent: January 4, 2022Assignee: Fraunhofer-Gesllschaft zur Foerderung der angewandten Forschung e.V.Inventors: Vincent Lorentz, Martin Maerz, Martin Wenger

Patent number: 10892466Abstract: The present invention describes an electrical energy storage cell with a bridging device. The energy storage cell has an at least partially electrically conductive housing (10), at least two terminals (11, 12) on the housing (10), of which a first terminal (12) is insulated from the housing (10) and a second terminal (11) is electrically conductively connected to the housing (10), and a bridging device, which can be actuated by an external signal to connect the two terminals (11, 12) of the energy storage cell electrically to each other. The energy storage cell is characterised in that the bridging device acts between the first terminal (12) and the housing (10) of the energy storage cell. A robust construction which is inexpensive to assemble can be implemented as a result.Type: GrantFiled: May 16, 2017Date of Patent: January 12, 2021Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Reinhold Waller, Vincent Lorentz, Martin Maerz

Patent number: 10784496Abstract: An electrical bypass device has two electrical conductors electrically insulated from one another and arranged such that two surface regions of the conductors are spaced apart from one another by a gap. Above the surface regions is a bypass element having at least one electrically conductive layer in the form of or connected to a mechanical energy store. The mechanical energy store is transferable by thermal triggering from a first mechanical state to a stable second mechanical state in which the electrically conductive layer of the bypass element makes electrical contact with the surface regions and shorts the two electrical conductors. Above the surface regions is a reactive element where an exothermic reaction can be triggered, resulting in the mechanical energy store transferring to the stable second mechanical state.Type: GrantFiled: May 15, 2017Date of Patent: September 22, 2020Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Reinhold Waller, Vincent Lorentz, Martin Maerz

Patent number: 10763595Abstract: The present invention relates to an electrical bridging device comprising two electrical conductors which are electrically isolated from each other and arranged such that two surface regions of both conductors are separated from each other by a gap. The two surface regions are each covered with a layer composed of an electrically conductive material which has a lower melting point than the electrodes. A reactive layer in which an exothermic reaction can be triggered is arranged above the two layers. The gap between the two surface regions is selected and the reactive layer is dimensioned and arranged such that the two layers which are composed of the electrically conductive material fuse at the gap due to the thermal energy which is emitted during the exothermic reaction of the reactive layer and consequently an electrical connection is created between the electrical conductors.Type: GrantFiled: November 17, 2016Date of Patent: September 1, 2020Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Reinhold Waller, Vincent Lorentz, Martin Maerz

Patent number: 10186734Abstract: A semiconductor substrate has a first doping region arranged at a surface and a second doping region adjacent to the first doping region. A p-n junction between the doping regions is at least partially arranged less than 5 ?m away from a contact area of the first doping region arranged at the substrate surface. A first contact structure is in contact with the first doping region in the contact area of the first doping region and has at least partially an electrically conductive material provided for a diffusion into the semiconductor substrate. The first contact structure is configured so that the conductive material provided for a diffusion into the substrate diffuses at least partially through the first doping region into the second doping region in case predefined trigger conditions occur. A second contact structure is in contact with the second doping region in a contact area of the second doping region.Type: GrantFiled: May 22, 2015Date of Patent: January 22, 2019Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Tobias Erlbacher, Vincent Lorentz, Reinhold Waller, Gudrun Rattmann
